HYDROCARB'ON-TORCH.

SPECIFICATION forming part of Letters Patent No. 717,831, dated January6', IQOS.

Application filed August 26, 1902,

To all whom it may concern.-

Be it known that I, CHRISTIAN FILZER, a citizen of the'United States,residing at Erie, in the county of Erieand State of Pennsylfl Vania,have invented certain new and useful Improvements inHydrocarbon-Torches; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to improvements in hydrocarbon-torches, and haslfor its object the production of a torch adapted for burn ing, brazing,dre., wherein heat Afor Vaporizing the fluid hydrocarbon is suppliedbyan auxiliary burner.

The features of this invention are hereinafter set forth and described,and illustrated in the accompanying drawings, in which- Figure 1 inview, partially in elevation and partially in section, of my improvedhydrocarbon-torch. y lEig. 2 is a top or plan view of the iireback of mydevice.

In the drawings illustrating my invention,` A is the upright body,within which is an annular shell B, joined at the top and bottom thereofto the bodyA by means of flanges a a', so as to form an annular chamberA' suitable for holding hydrocarbon fluid. In one side of the chamber Athere is an upright pipe C, extending from near the bottom of thechamber B through the upper ilange oz, where it joins the end of a pipeD, which extends downward within the central opening B' inside of theshell B and is coiled back upon itself so as to form a coil of pipe D',the upper end of which connects with an opening c in the spider E,secured to the iiange a at the top of the body A. The body A extendsdownward below the flange a and forms a chamber A2 for the lamp-burner Eand is perforated with openings a2 around the burner F, so as to furnishair thereto. The burner F is secured to a base G, which forms afluidtank to supply the burner F and also operates as the base of thebody A. The base Gr is provided with a projection G' at one side, fromwhich a stem g extends up into the hol- Serial No. 121,949. (No model.)

low handle II, secured to one side of the body A, where it is providedwith a retractingspring h, whereby the base G can be moved downwardfromthe body A, as illustrated in dotted lines in Fig. 3, and swung aroundto one side of the body4 A, as illustrated in Fig. 2, the object of thisconstruction being that the lamp-burner F operates to heat the inside ofthe shell B, so as to sufficiently vaporize the fluid hydrocarbon in thechamber A' to produce pressure enough therein to force the fluid upthrough the pipe C and down luto the coil D', which is also heated bythe lampburner E sufficiently to completely vaporize the iiuid, whichpasses from the upper end thereof through the opening e to thevalvechamber I of a burner or burners J, secured 'to the top of thespider E. The burner .I is

of the usual construction, and itis obvious that a plurality of burnersmay be connected with the opening e in the spider E and operate with thesame facility as the single burner J shown in the drawings.

Covering the spider E and the shell of the valve-chamber I thereis acover K, which is secured to the top of the body A and is provided withopenings awhich operate as escape-vents for the products of combustionfrom the lamp-burner F. This cover K also concentrates the heat from thelamp-burner F upon the valve-chamber I and retains the vapor produced inthe coil D at a'high temperature until it passes to the burner.

Connected with one side of the passage e there is a small safety-valveL, which' operates when undue pressure is produced in the coil D topermit the vapor to blow off and escape, and at one side of the body Athere is a supply-pipe M, with a suitable closure for filling thechamber A', and on the opposite side of the body A there is a pipe N,provided with a shut-off cock n, to which pipe an airpump can beattached in case it is desired to pump air into the chamber A. At oneside of the body A there is also an inlet-Q, provided with a valve q,which may be connected by means of suitable pipes with a tank (notshown) of hydrocarbon iluid when a greater quantity thereof than thechamber A' will hold is needed to complete any desired opera- Ition.

On the upright body A, opposite the han-` IOO die H, there is a clamp O,in which a irebacksupport P can be secured, and upon the snpport P thereis adjustably secured a reback R, which can be adjusted in front of theburner J, as desired. The inner surface of this lreback is provided Withan asbestos lining R', so that it will resist the heat of the ame fromthe burner J.

I have thus shown and described a convenient construction of myinvention which will enable others to utilize the same. It is, however,obvious that its construction can be modified in many respects Withoutdeparting from the spirit of my invention.

Therefore what I claim as new, and desire to secure by Letters Patent ofthe United States, is-

l. The combination in a hydrocarbon-torch, of a body having anannularchamber for Huid hydrocarbon, a vaporizing-coil in the openingformed by the inside Wall of said chamber, a pipe connecting one end ofsaid coil with the lower part of said chamber, a valve-chamber, valveand burner connected with the upper end of said vaporizing-coil, and alamp-burner undersaid Vaporizing-coil adapted to heat the inside Wall ofsaid chamber, and said vaporizing-coil, substantially as set forth.

2. The combination in a hyd rocarbon-torch, of a Vertical body, aninside vertical Wall connected at its top and bottom With the body so asto form an annular chamber between the 'inside of the body and saidinside Wall and also a central vertical passage within said inside wall,a base under said body having a fluid-tank therein, a lamp-burner on thetop of said base directly under said vertical passage, a vaporizing-coilin said vertical passage, one end of which connects with a pipe leadingdown into said annular chamber, a valvechamber mechanism connected Withthe opposite end of the Vaporizing-coil, and a burner mechanismconnected with said valve-chambersubstantially as set forth.

3. The combination in a hydrocarbon-torch of a vertical body havingtherein an annular chamber, and a central vertical passage, a basehaving a fluid-tank therein and adapted to be swung to one side of thebody, a lampburner on said base under the central vertical passage insaid body, a pipe leading down into said annular chamber, avaporizing-coil Within said central vertical passage connected at oneend with said pipe, a valve mechanism and burner connected with theopposite end of said coil, and a cap on said body covering said valvemechanism, and having draftopenings therein, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

CHRISTIAN FILZER.
